Automatic Street Light Control Project

In Automatic Street light control project for on & off using light dependent resistor, we developed an automatic energy efficient device using micro controller based on light dependent resistor.

In recent day’s energy efficient control systems are gaining importance due to the implementation of embedded systems in the field of automation technologies, the key elements of the embedded systems are micro controllers.

The streets are automatically switched on when the light intensity falls below the threshold value, and the intensity of the light is sensed by the light sensors i.e. light dependent resistors, light dependent resistor exhibits high resistance under sufficient light and acts as an conductor i.e. low resistance path in times of low light intensity periods. This entire process is monitored by a micro controller based on the signals from the light dependent resistor.

Hardware components:

Micro controller – low power high performance 18F452 Microcontroller is used in the project which manipulates the circuit based on the light dependent resistor.
